Title:
ENCODER SYSTEM, MOTOR SYSTEM, AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/024706
Kind Code:
A1
Abstract:
A system in which a power supply voltage is supplied from a common power supply circuit to a plurality of encoders is configured such that a fault location in power supply wiring can be easily identified. The system is provided with: an encoder power supply circuit 12 for generating a power supply voltage; individual power supply wires 54 each provided for each encoder 52 to supply the power supply voltage and having one end connected to the encoder; switches 22 each provided for each individual power supply wire 54 on the other end side of the individual power supply wire 54 to switch between connection to and disconnection from the encoder power supply circuit 12; and voltage detection circuits 23 each provided for each individual power supply wire 54 and disposed closer to the encoder 52 than the switch 22 at the other end side of the individual power supply wire.
